In anime, the line between hero and villain is rarely as clear as it seems. Some of the medium’s most iconic protagonists started out with noble intentions like fighting for peace, freedom, or love, only to reveal darker motives or actions that challenge the very definition of heroism. These characters earn our admiration, but often at a cost that exposes a far more complicated truth.
Whether driven by revenge, power, or twisted ideology, these “heroes” force audiences to reconsider what it truly means to do good. In some cases, their villainy emerges gradually. In others, it is baked into their core from the start, hiding behind charm or moral ambiguity. From mind-controlling revolutionaries to blood-soaked saviors, here are eight anime characters who prove that not all heroes wear white hats, some of them wear masks, cloaks, or even crowns soaked in blood.
Shigure
From Fruits Basket by TMS Entertainment; Based on the Manga by Natsuki Takaya
At first glance, Shigure Sohma appears to be a harmless flirt and comic relief in Fruits Basket. As the older cousin who takes Tohru in, he’s often lounging around in a robe, making jokes and offering sage advice. But beneath that laid-back exterior lies a man whose long game is far more manipulative than it appears.
Shigure’s goal is not just peace for the cursed Sohma family, it is personal. His pursuit of Akito, the god of the zodiac, reveals a willingness to emotionally wound others, even close friends, to get what he wants. He pushes characters into uncomfortable confrontations and orchestrates events with a cold, calculated detachment. In the end, he is not saving the Sohmas, he is playing god in his own twisted romance.
Su-won
From Yona of the Dawn by Pierrot; Based on the Manga by Mizuho Kusanagi
Su-won begins as a quiet and thoughtful friend to both Yona and Hak, someone who seems too kind to hurt a fly. But that illusion shatters when he murders Yona’s father, King Il, in cold blood and stages a coup to claim the throne for himself. Su-won does not act out of hatred, but that makes him more terrifying.
What cements Su-won as a villain disguised as a reformer is his belief that his vision for the kingdom justifies betrayal and bloodshed. He becomes a competent ruler and arguably a more effective leader than King Il. Yet, his cold-hearted methods and complete lack of remorse highlight his villainy. He may love Yona in his own way, but not enough to spare her father or her innocence.
Lelouch Lamperouge
From Code Geass: Lelouch of the Rebellion by Sunrise; Original Story by Ichirō Ōkouchi and Gorō Taniguchi
Lelouch vi Britannia is the very definition of a charismatic antihero. With his Geass power to control others, he wages a rebellion against the Holy Britannian Empire under the guise of Zero. His cause is noble, freedom from tyranny, but the way he achieves it is anything but righteous.
Lelouch sacrifices thousands, manipulates his own friends, and plays god with an entire nation’s future. His climactic plan, the Zero Requiem, is meant to bring about world peace, but only through his death and the illusion of a common enemy. It is brilliant, but undeniably cruel. Lelouch becomes the villain he once sought to destroy, proving that absolute power corrupts, even when wielded with good intentions.
Ken Kaneki
From Tokyo Ghoul by Studio Pierrot; Based on the Manga by Sui Ishida
Ken Kaneki’s descent into darkness is one of anime’s most haunting transformations. Once a shy, bookish college student, Kaneki becomes a half-ghoul after a tragic operation. Initially, he clings to his humanity, trying to reconcile his new identity with a desire to protect others. But the world around him doesn’t allow for half-measures.
Kaneki's villainy lies not in malice, but in surrendering to the monster within.
As Kaneki endures torture, loss, and betrayal, his morality erodes. He begins to embrace violence, rationalizing murder as a necessary evil in a brutal world. By the time he becomes the leader of Goat, he has lost sight of his original self. The lines blur completely when he allows others to die for his ideals. Kaneki's villainy lies not in malice, but in surrendering to the monster within.
Sasuke Uchiha
From Naruto by Studio Pierrot; Based on the Manga by Masashi Kishimoto
Sasuke Uchiha’s journey is marked by tragedy, revenge, and betrayal. Initially a proud but disciplined ninja, Sasuke’s single-minded desire to avenge his clan leads him to betray his friends and abandon Konoha. He aligns with Orochimaru, a known villain, and later vows to destroy the very village he once called home.
Even after learning the truth about his brother Itachi, Sasuke continues down a destructive path. His plan to become Hokage by force and “unify” the world through fear reeks of authoritarianism. Though he eventually finds redemption, Sasuke’s actions of murder, manipulation, and terrorism are undeniably villainous. His fall from grace is a case study in how pain and pride can warp a hero into an enemy.
Light Yagami
From Death Note by Madhouse; Based on the Manga by Tsugumi Ohba and Takeshi Obata
Light Yagami’s story is perhaps the most infamous example of a hero turned villain. A genius high school student with a strong sense of justice, Light discovers the Death Note and begins eliminating criminals to create a utopia. His goal seems pure, but his methods quickly reveal a god complex in the making.
By the end, Light is not saving the world, he is ruling it with fear.
As Light evades capture and eliminates anyone who gets in his way, he loses any shred of moral high ground. He manipulates innocent people, orchestrates murders, and lies to everyone, including his own family. By the end, Light is not saving the world, he is ruling it with fear. His descent shows how the pursuit of justice without empathy becomes tyranny in disguise.
Eren Yeager
From Attack on Titan by Wit Studio and MAPPA; Based on the Manga by Hajime Isayama
Eren Yeager begins Attack on Titan as a symbol of defiance and hope. Driven by the trauma of losing his mother and the desire to eradicate Titans, Eren is an easy character to root for. But as the series progresses, his ideals become more radical, and his methods more horrifying.
By the final arc, Eren is no longer the wide-eyed boy who dreamed of freedom. He initiates the Rumbling, a global genocide, to protect Paradis Island. Eren Yeager's transformation from freedom fighter to mass murderer is chilling. Eren justifies his actions as preemptive defense, but the scale of destruction he unleashes brands him a villain. His tragedy lies in how much he believed he was saving the world, even as he destroyed it.
Griffith
From Berserk (1997, 2016, and Film Series) by Various Studios; Based on the Manga by Kentaro Miura
Griffith is perhaps the most universally reviled “hero” turned villain in anime. As the leader of the Band of the Hawk, he is brave, charismatic, and visionary. Guts, Casca, and many others follow him with unwavering loyalty. But Griffith’s ambition is boundless, and when he sees his dream slipping away, he makes a choice that damns him forever.
During the infamous Eclipse, Griffith sacrifices his comrades to become a demonic god-hand known as Femto. He commits atrocities that go beyond betrayal because he started violating, murdering, and destroying those who trusted him most. Unlike others on this list, Griffith’s transformation is not gradual; it is monstrous and absolute. He was never truly a hero, just a man who hid his darkness behind a dazzling smile.
